spotting at 5 weeks - tips please!

Dawn
Almost 5 weeks pregnant with my rainbow and I'm having some orange spotting today. I blocked it out of my memory what my spotting was like with my mc in August. 
Help, What are good or bad things to look for?
 This is my 5th pregnancy and my 3 healthy babies never had a drop of spotting without explanation; rough sex or drs visit. I'm so scared. I just want this baby 💗
